前置准备
-
防火墙配置(选择一种操作)
- firewall防火墙
firewall-cmd --permanent --add-port=5432/tcp firewall-cmd --permanent --add-port=123/udp- iptables防火墙
iptables -A INPUT -p tcp --dport 5432 -j ACCEPT iptables -A INPUT -p udp --dport 123 -j ACCEPT- 直接关闭防火墙
systemctl stop firewalld.service systemctl disable firewalld.service systemctl stop NetworkManager.service systemctl disable NetworkManager.service -
关闭 SELINUX
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
setenforce 0-
检查时间和时区
[root@localhost lib64]# timedatectl
Local time: 五 2023-01-06 16:06:20 CST
Universal time: 五 2023-01-06 08:06:20 UTC
RTC time: 五 2023-01-06 08:06:20
Time zone: Asia/Shanghai (CST, +0800)
NTP enabled: yes
NTP synchronized: yes
RTC in local TZ: no
DST active: n/a
如果需要修改可以执行：
#时区列表
$ timedatectl list-timezones
#设定时区
$ timedatectl set-timezone Asia/Shanghai-
安装依赖包
以下执行命令过多，可以创建一个bash可执行文件，统一运行(示例)
$ touch pack.sh
$ vi pack.sh
$ chmod 777 pack.sh
$ ./pack.sh

创建 lightdb 用户并设置 sudo 免密
#创建组(lightdb)
$ groupadd lightdb
#创建用户(lightdb)
$ useradd -g lightdb -m lightdb
#设置密码
$ passwd lightdb
#设置免密
#修改sudoers文件权限
$ chmod 755 /etc/sudoers
$ vi /etc/sudoers
追加一行：lightdb ALL=(ALL) NOPASSWD: ALL
$ chmod 440 /etc/sudoers-
创建 LightDB 安装目录和实例目录
#创建安装目录
$ mkdir -p /usr/local/lightdb
# 修改目录所属用户和组
$ chown -R lightdb:lightdb /usr/local/lightdb
实例目录默认路径为：安装目录下
修改默认实例目录示例：
$ mkdir -p /data/lightdb_data
$ chown -R lightdb:lightdb /data/lightdb_data-

- 虚拟机centos7配置 DISPLAY 环境变量
#命令格式
export DISPLAY=Windows IP:0.0
#IP为运行Xmanager-Passive的系统IP
#【:】后的值为Passive运行后的状态提示，通常为0.0
# 以下命令在lightdb用户下执行
$ export DISPLAY=10.188.122.214:0.0- 安装GUI依赖包
yum install -y libXtst gtk2 libX11- 执行安装脚本
$ ./install.sh
